Osama bin Laden's chief deputy on Tuesday denied a theory that Israel carried out the Sept. 11 attacks and blamed Iran and Shiite Hezbollah for spreading the idea to discredit the Sunni al-Qaida's strike against the U.S.

[..]

One of the questioners asked about the theory that has circulated in
the Middle East and elsewhere that Israel was behind the 2001 attacks
on the World Trade Center and the Pentagon.

Al-Zawahri accused Hezbollah's Al-Manar television of starting the rumor.

"The purpose of this lie is clear — (to suggest) that there are no
heroes among the Sunnis who can hurt America as no else did in history.
Iranian media snapped up this lie and repeated it," he said.

"Iran's aim here is also clear — to cover up its involvement with America in invading the homes of Muslims in Afghanistan and Iraq," he said.

And Iraq and Afghanistan and their tragedies; and the
reeling of many of you under the burden of interest-related debts,
insane taxes and real estate mortgages; global warming and its woes;
and the abject poverty and tragic hunger in Africa; all of this is but
one side of the grim face of this global system.

Dennis Kucinich? Naomi "No Logo" Klein? Daniel "Dany the Red"
Cohn-Bendit? If you guessed "none of the above," you are either an
astute observer of the anti-globalization movement, or you have already
read a transcript of
Osama Bin Laden's latest video production. If so, you will also know
that Bin Laden, after denouncing the "capitalist system," which "seeks
to turn the entire world into a fiefdom of the major corporations,"
calls for Americans to convert to Islam because, among other things,
taxes are lower in Islamic states. It's a genuinely bizarre, almost
ridiculous document—and before it is forgotten in the coming debate on
Gen. David Petraeus' Iraq report, it's worth spending a few minutes, on
the sixth anniversary of Sept. 11, trying to understand what it might
mean.

Real or fake, the message might still hint at the direction in which
al-Qaida propaganda, or at least al-Qaida propaganda designed for the
Western market, is now heading. In a recent Slate piece, Reza Aslan eloquently described how the organization's list of alleged "grievances"—which
now include global warming, corporate capitalism, and African poverty,
as well as the American bases in Saudi Arabia—weave "local and global
resentments into a single anti-American narrative, the overarching aim
of which is to form a collective identity across borders and
nationalities."

Using the left's argument's and grievances to court and win sympathy and support. Not the newest trick for islamists, but a very effective one historically, starting with the Iranian revolution and passing by the support of Kefaya to the Muslim Brotherhood and ending with the current direction of the collaboration of the left and the islamists to counter the great american empire. The sad thing is, the islamists always screw over the leftists eventually, and the leftists never learn.
